Here is a taste of Ryan Burge’s recent study (bold type is his, not mine):
Clearly, the conclusion that emerges here is that liberal Christians are more politically active. In the case of attending political meetings, such as school board or city council meetings, and putting up political signs, the difference between liberal and conservative Christians wasn’t significant. But in the other four activities, the gaps tend to be fairly robust.
A liberal Christian was more than twice as likely to attend a protest or march (13% vs 5%), six points more likely to contact a public official, eleven points more likely to donate money to a candidate (38% vs 27%) and twice as likely to volunteer their time for a candidate or campaign. Pretty hard to say that conservative Christians are more active when looking at this first graph. It’s the liberal Christians that seem to be engaging in the most laborious type of political activity.
